Yeah, with rare exceptions, my production birds all tended to die at around 2-3 years of age, usually to some horrible and incurable malady related to their high production.That's the reason I won't get those types of birds anymore. Too much heartbreak!
In my experience, both breeding for high production and inbreeding while working toward a standard can produce birds with shortened lifespans, though. So breeder birds are less likely to have those egg laying maladies because they're less bred for extreme production, but they can still end up with issues from the shallowness of the gene pool they come from due to selection for a standard. That's one reason why I chose a clan-style breeding setup for my Cochins, with the hopes that it would prevent an inbreeding depression and make the birds I produce a bit hardier.A good breeder should be taking into consideration the health of their birds as well, though, so unless it's a very rare breed where inbreeding is just an inherent issue and will continue being one until more people get involved and more flocks branch out away from the original ones, breeder birds tend to live longer and be hardier than production birds in my experience.
Golden Comets are a high-production egg laying hybrid, so unfortunately are prone to fizzling out early. Sorry you had to go through that!![]()
Yup, year 2 and three is when the first problems start to arise, in my experience. You're lucky to get one to 4 years old. When I first started, that was the normal lifespan. Now it's even less. The last batch struggled to reach age 3/3.5 well put on proper breeding practices. Just mixing doesn't always help (as can be seen with the billion mixes here that are so unhealthy), but considerate mixing with another line (or breed, if the goal isn't a pure bird) is very helpful. I've read about clan breeding before, but haven't fully understood the mentality behind it, and how to implement it. Could you possibly explain it? I'm thinking of implementing this breeding strategy with the serama for next year
